| Title: | Along-channel velocity and calculated total suspended sediment measurements using an acoustic doppler velocimeter (ADV) in the Gulf Intracoastal Waterway at Larose, Louisiana from 2022-04-21 to 2022-05-01 (NCEI Accession 0276517) |
| Abstract: | An acoustic doppler velocimeter (ADV) was deployed in the Gulf Intracoastal Waterway (GIWW) near Larose (LA) using a 6000 kHz Nortek Acoustic Doppler Velocimeter (ADV). The cross section is about 75 m wide, with a depth of ~4.5 m toward the center and ~4 m toward the side. The instrument was deployed about 3 m from the bank, where the water depth is about 4 m. The three-dimensional velocity was recorded 0.4 m above the bed. Both the 3-dimensional velocity and the backscatter was recorded continuously at a frequency of 8 Hz. In post-processing, data were converted into bursts of 16 seconds, which were then averaged to give a single measurement per burst. The backscatter signal-to-noise ratio (S) [dB] was converted to TSS [mg/l] using a laboratory-calibrated formula (TSS=10^(0.052S+0.04). A text file of the calculated TSS (mg/l) and along channel velocity (m/s) at depth is provided along with a .hdr that describes the headers of each file provided, a .dat that describes the data configuration from the instrument, and a .sen file that describes the instrument set up. |
